In this study, a unique receiver design is given for consideration. The interior of the receiver is constructed out of aluminium, while the exterior is built of copper. The water that is held within the inner copper tube is heated by a system that circulates through it, and the hollow area that is found between the two tubes is filled with vegetable oil to decrease the amount of heat that is lost. As a direct consequence of this, low-pressure steam is generated. The efficiency of the system was evaluated in comparison to the performance of another receiver made up of the same number of tubes (aluminium). The receiver that was built with tubes made of different metals had an initial efficiency of 58.61, whereas the receiver that was built with the same type of metal had an efficiency of just 36.5. In conjunction with this study, integrated solar still found that due to Al-Al's introduction of this still interaction, the receiver of the parabolic trough collector has a lower efficiency. The still with the parabolic trough collector has a daily average efficiency of 52.25, whereas the still without the collector has a daily average efficiency of 36.36. © 2023 The Author(s)
